eduardoh se confundiu.
União é a soma dos conjuntos, ou seja 1;2;3;.
Intersecção é a parte que pertence aos dois conjuntos ao mesmo tempo, ou seja 2 e 3.
É isso!

    [3;2] não é intervalo pois 3 > 2. vc deve ter escrito ao contrário.

    [2;3] união [1;3] = [1;3]

    [2;3] interseção [1;3] = [2;3]
